   but the error is PAGE_FAULT_IN_NONPAGED_AREA
   
   Code you write does not get to handle this error gracefully. This is the kernel shooting it in the head. This is not something Rust magically solves. I literally reported an issue a couple weeks ago to a Rust program that was having this same problem on FreeBSD
   
   pid 10464 (qdrant), jid 113, uid 0: exited on signal 11 (no core dump - bad address)

     @feld @SlicerDicer @javierg @marcan I am assuming freertos doesn’t have process isolation since it’s running on microcontrollers? An out of bounds write would just corrupt stuff that maybe would crash later

     @SlicerDicer @javierg @marcan yeah but you're working in a RTOS with a microcontroller which is a much more constrained environment where you're probably doing static memory allocations too -- completely different computing environment

     @feld @marcan @javierg What about the life support system I’m building that is not memory safe.
     
     It’s a matter of handling gracefully yes. That’s all it truly is. Whatever that condition may be. It’s the job of the developer to ensure this is robust enough.
